Reks has white-blond hair and pale blue eyes. He wears a short leather shirt that bares his midriff, curved pieces of armor either side of his neck; plated bracers and leather fingerless gloves, strips of leather round his waist with a groin protector, black trousers under metal and leather greaves, and flat brown shoes with the toes cut away. A blue brooch upon his chest resembles the one his brother Vaan wears, and in a dream sequence it is implied he also left Vaan a silver ring with a blue motif. In the Final Fantasy XII manga it is revealed Vaan's chestplate originates from Reks.
